Yes, people like that usually fail to understand that most of us "tech" geeks here are the ones SUPPORTING the "businessmen" and having to listen to their mad demands for all types of functionality.
To quote a good friend of mine who works in the DoD in the D.C. area: "Hi, I'm an information technology specialist. We run sh1t now."
(It's a line from some movie as well I think)

Maybe "businessmen" in the UK and Europe need handheld fax capability, but everywhere else I've been on the planet (Middle East, Africa, Asia, and the US) they want email and have ditched their fax machines for digital senders, namely HP's line of digital senders. I think I've setup a few hundred of those over the years.
Face it, the ONLY reason folks want fax capability like that is to scan in a document and have it on their device. That's why digital senders are going to pretty much replace fax machines in ten years time. They eventually pay for themselves over time what with getting rid of a dedicated phone line and being able to scan in and eventually mass store paper documents.

The BIGGEST complaints I've heard about portable devices have been in regards to digital signatures/signing/encryption support. Particularly the lack of "options" when it comes to hardware PKI tokens (read: smart cards) since right now the Blackberry has that one sewn up with the CAC sleds (both bluetooth and attached sleds). Nokia can hit it HUGE in the business world if they would just develop and market to the U.S. Government a bluetooth or attached smartcard reader sled for their E-series phones. Well, that and get their phones through the NSA testing process for supported encryption techniques. Because once you get the U.S. Gov, you get all those contracting companies as well....Northrupp Grumman, Boeing, DynaCorp, Halliburton, etc.

As long as a device supports PKI functionality in addition to email, contacts, and calendar then the "businessmen" I work with are pretty frickin' ecstatic.
And now I'm starting to get questions "about this VoIP thing on cell phones" since we're running VoIP at work now. (read: management looking to save a few extra bucks that better be going to my damned EOY bonus!)
I got so many requests/questions about the iPhone that I basically wrote up a little internal memo and sent it around to everyone about how they will HATE an iPhone and what it DOESN'T offer them compared to their current phones.
That pretty much killed their lust for it instantly.
